The study area is located in the south of Iran in the vicinity of the world largest Makran Accenary Wedge. In this study we investigated the coloration between the the airborne geomagnetic (7.5 km) derived lineament and the seismicity of the region close to Bashagard. To utilize the gem agnatic data a processing of it has been considered. Among the processing the Filtering such as turning to pole, vertical derivation and tilt filters and total magnetic field intensity map has been applied. The trend of the structure's are being identified in the study area. Further the seismicity of the region has been extracted from the bulletin of seismology belong to the institute of geophysics, University of Tehran. For the geomagnetic analysis we used the GeoSoft Oasis Montaj 6.4.2 Software. The achieved result is very promising and there a very goo's correlation between the magnetic lineament location and the occurred seismicity.
